The current Thunderbolt I have was a replacement for the original. I cracked my screen and had the phone replaced, which I'm sure is a refurbished phone. Here are my issues: 1. Battery life ( which is the most obvious one) 2. When there is no 4G, the 3G barely lets me on the internet. 3G connectivity sucks 3. The phone will get incredibly hot after a while, which I'm sure has to do with battery 4. Sometimes texting is an issue. It seems to gets stuck at times and sending media such as pics will not send at times I know the last update was supposed to fix a lot of these issues but i never got it. I still check for it everyday and nothing. Any ideas what I should. Should I call Verizon? Should I call HTC. This phone is great when there is 4G or WiFi around, but going away it becomes a problem. Advice please!
